You mean the boots on top of the tower with the static clouds around the coast from the Winnebago? You don't have to do anything else - just teleport yourself up there.
If you mean the gloves behind the blue barrier (in another tower after the maze) then I don't see where teleport come into it - you need to remove the barrier and then have enough strength to get them.
To remove the barrier you need to
Can't think the other pieces are in towers at all - if you are still stuck say which is the "last piece" you are after.
